SHOREA ROBUSTA GAERTN.F.(SAL) IN THE FORESTRY OF NEPAL

The distribution, silvicultural characteristic, growth rate and economic importance of S. robusta Gaertn.f., an indigenous hardwood species in Nepal, were analysed. The natural S. robusta forests in the southern plain of Nepal (the Bhabar-Terai) have been seriously degraded during the past decades. Forest inventories and trials in Nepal have revealed a good regeneration potential foe the existing S. robusta forests. After regeneration felling the new S. robusta crop reaches a standing stem volume of 100 m3 ha-1 in ten years. With an average site quality of I/II, the maximum mean annual increment of stemwood (15 m3 year-1) is reached after 25 years and the maximum sawlog size wood MAI (5.7 m3 year-1. 20 cm top, under bark) after 60-70 years. The productivity of the dense naturally regenerated young forests is on a par with the commonly planted species in Nepal.
